Abstract
A method of a user equipment (UE) for an uplink power control is provided. The method comprises transmitting, to a base station (BS), UE capability information including a full power transmission capability of the UE, receiving, from the BS, downlink control information (DCI) including a transmit precoding matrix indicator (TPMI), determining a power level for each antenna port at the UE based on the full power transmission capability of the UE and the TPMI, and transmitting, to the BS, UL data via physical uplink shared channel (PUSCH) based on the determined power level for each antenna port at the UE and the TPMI wherein the TPMI indicates a precoding matrix and a number of layers used to transmit the UL data via the PUSCH.
Claims20
A user equipment (UE) for an uplink (UL) power control, the UE comprising
- a transceiver configured to:
- transmit, to a base station (BS), UE capability information including a full power transmission capability of the UE, and
- receive, from the BS, downlink control information (DCI) including a transmit precoding matrix indicator (TPMI);
- and
- a processor operably connected to the transceiver, the processor configured to determine a power level for each antenna port at the UE based on the full power transmission capability of the UE and the TPMI,
- wherein the transceiver is further configured to transmit, to the BS, UL data via physical uplink shared channel (PUSCH) based on (1) the determined power level for each antenna port at the UE, and (2) the TPMI, where the TPMI indicates a precoding matrix and a number of layers used to transmit the UL data via the PUSCH.
A base station (BS) for an uplink power control, the BS comprising:
- a processor;
- and
- a transceiver operably connected to the processor, the transceiver configured to:
- receive, from a user equipment (UE), UE capability information including a full power transmission capability of the UE,
- transmit, to the UE, downlink control information (DCI) including a transmit precoding matrix indicator (TPMI), and
- receive, from the UE, UL data via physical uplink shared channel (PUSCH) based on (a) a power level determined for each antenna port at the UE, and (b) the TPMI, where the TPMI indicates a precoding matrix and a number of layers used to transmit the UL data via the PUSCH, and the power level determined for each antenna port at the UE is determined based on the full power transmission capability of the UE and the TPMI.
A method of a user equipment (UE) for an uplink power control, the method comprising:
